On the Hausdorff stability of barcodes over posets

Mujtaba Ali, Tom Needham, Anastasios Stefanou +1

The Isometry Theorem of Chazal et al. and Lesnick is a fundamental result in persistence theory, which states that the interleaving distance between two one-parameter persistence m…

Algebraic Zhou valuations

Shijie Bao, Qi'an Guan, Lin Zhou

In this paper, we generalize Zhou valuations, originally defined on complex domains, to the framework of general schemes. We demonstrate that an algebraic version of the Jonsson--M…

Persistence and Topological Complexity

Facundo Mémoli, Ling Zhou

Topological complexity is a homotopy invariant that measures the minimal number of continuous rules required for motion planning in a space. In this work, we introduce persistent a…

Doughnut or Mickey Mouse? Detecting Toroidal Structure in Data through Persistent Cup-Length

Ekaterina S. Ivshina, Galit Anikeeva, Ling Zhou

Understanding the structure of high-dimensional data is fundamental to neuroscience and other data-intensive scientific fields. While persistent homology effectively identifies bas…

Persistent Sullivan Minimal Models of Metric Spaces

Ling Zhou

We extend classical tools from rational homotopy theory to topological data analysis by introducing persistent Sullivan minimal models of persistent topological spaces. Our main re…

Torsion higher Chow cycles modulo

Theodosis Alexandrou, Lin Zhou

We study the injectivity property of certain actions of higher Chow groups on refined unramified cohomology. As an application for every and for each and $n\ge…
